Abstract

The present invention provides a method and device for sending BFD messages. The method includes: determining the attribution information of each member interface in an aggregation interface; wherein, the attribution information of the member interface is used to identify the sub-card to which the member interface belongs, and the sub-card to which the sub-card belongs. The line card and the box to which the line card belongs; select the member port that sends the BFD message according to the attribution information of each member port, so that the attribution information of the member ports that send the BFD message twice consecutively is inconsistent. The application of the embodiments of the present invention can improve the accuracy of judging the state of the aggregation interface.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a BFD message sending method and device. Background technique [0002] With the development and progress of the network, the requirements for the reliability of network equipment and fast convergence of faults are increasing. [0003] Currently, aggregation and bidirectional forwarding detection (English: Bidirectional Forwarding Detection, BFD for short) are mainly used to improve device reliability and complete rapid convergence. The device can detect faults at the millisecond level through the BFD function. When BFD cooperates with the aggregated interface, if the aggregated member interface fails, joins or exits the aggregated interface, BFD may lose packets continuously due to timing issues or / and the BFD packet sending mode. , causing the device to misjudge the status of the aggregation interface, and then the aggregation interface protocol flaps due ...
